Operator TriMet relies on rail technology from Siemens for newly opened light rail line

14.09.2015
  • MAX Orange Line between Portland and Milwaukie
  • 18 light rail vehicles S70 type energy
  • Energy storage system type Sitras SES
  • Signaling and communication system

Today, TriMet's new MAX Orange Line, a light rail project between Portland and Milwaukie (USA), was officially inaugurated. Siemens advanced rail technologies are now operating on the Orange line including its S70 light rail vehicles designed and manufactured at Siemens Sacramento, California plant to move riders along the system, rail signaling and communication systems to help manage train operation, and the company's first Sitras SES energy storage unit in the U.S. that uses regenerative braking to sustainably power the line.


The 7.3-mile (around 12 Kilometer) MAX Orange Line is the region's sixth construction project of the development project Metropolitan Area Express (MAX) to expand the city's transport network to cope with the expected population growth in the Portland area. The line will improve transit in the corridor that extends from the terminus of the MAX Green and Yellow lines at Portland State University in Downtown Portland to Milwaukie and North Clackamas County.

"Siemens is proud to be a technology partner for Trimet for more than 30 years, starting in the this project is a perfect example of how advanced rail technologies can help to revitalize city centers, creating jobs and stimulating economic development", said Jochen Eickholt, CEO Siemens Mobility Division.

The newly redesigned light rail vehicles were built based on input from TriMet and riders, featuring new seating arrangements, additional wheelchair accessibility, larger windows and improved HVAC systems that automatically adjust based on the number of people in the vehicle.

The vehicles also include better sight lines for the driver, more ergonomically designed main cabins, and larger displays for train operators so they are better able to monitor the vehicle's status to improve safety and efficiency. Maintenance enhancements were made based on TriMet's feedback including rearrangement of systems to increase accessibility to key components on the vehicles and improved diagnostic systems.

The innovative regenerative rail energy storage technology allows for energy created during braking to be stored and then re-used in one of two forms, energy savings or voltage stabilization during peak demand times. TriMet will utilize the system in voltage stabilization mode. In this mode, the storage unit allows the system to avoid problems disruptions that can occur in mass transit operations if power drops below a certain level.

If a number of vehicles accelerate simultaneously, system voltage can drop below a critical level and result in instances of under-voltage tripping in vehicles and, consequently, lead to disruptions in passenger service. The Sitras SES ensures the system voltage always remains within the required range and voltage-related disruptions no longer occur.

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...

Im Focus: How Do the Strongest Magnets in the Universe Form?

How do some neutron stars become the strongest magnets in the Universe? A German-British team of astrophysicists has found a possible answer to the question of how these so-called magnetars form. Researchers from Heidelberg, Garching, and Oxford used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.
